Meshed seat cushion for chair

ABSTRACT

A novel meshed seat cushion is provided herein which contains at least a bottom member, a meshed member, a rim member, and a number of elastic members. The bottom member has a basin shape with a number of supporting elements along two opposing sides of the bottom member so as to suspend the elastic members across the top of the bottom member and beneath the meshed member. Each of the elastic members has at least an elongated flexible element with locking elements at its two ends. The meshed member covers the top and the top rim of the bottom member and is framed and fixed to the bottom member by the rim member and the application of a number of bolts. The elastic members not only improve the comfort of the user, but also provide support to the meshed member  4  so that it wouldn&#39;t deform after a long period of usage and the operational life of the meshed seat cushion is therefore extended significantly.

BACKGROUND OF THE INVENTION

(a) Technical Field of the Invention

The present invention generally relates to chairs, and more particularlyto a meshed seat cushion for a chair.

(b) Description of the Prior Art

The seat cushion and/or backrest of a chair are sometimes designed to bemeshed ones so as to facilitate ventilation and to enhance the comfortof a user. FIG. 1 is a perspective diagram showing a conventional chairhaving meshed seat cushion and backrest. As illustrated, the chair 1mainly contains a backrest 11, a seat cushion 12, and a stand 13.

The backrest 11 has a frame 111 and a meshed member 112 wrapping up theframe 111 and fixed to the frame 111 by bolts. The seat cushion 12, asshown in FIG. 2, contains a seat bottom 121 having an open top and anumber of bolt holes 1211 around its top rim, a meshed member 122, and arim member 123. The meshed member 122 is configured to cover the opentop of the seat bottom 121 and is fixed to the rim member 123 byscrewing the bolts S through the bolt holes 1211 and the meshed member122. The stand 13 has a number radial legs 131 with rollers 132 at theends to support the seat cushion 12 and the backrest 11 on the groundand for easy moving.

Conventionally, the meshed member 122 is elastic to fit the specificposture of a user. However, as the user's entire weight is placed uponthe seat cushion 12, the meshed member 122 would deform after a periodof usage and the comfort provided by the chair 1 is seriously impaired.

SUMMARY OF THE INVENTION

The primary purpose of the present invention is to provide a novelmeshed seat cushion to obviate the disadvantages of conventionaldesigns. The meshed seat cushion contains at least a bottom member, ameshed member, a rim member, and a number of elastic members. The bottommember has a basin shape with a number of bolt holes around its top rimand, inside the bottom member, there are a number of supporting elementsalong two opposing sides of the bottom member so as to suspend theelastic members across the top of the bottom member and beneath themeshed member. Each of the elastic members has at least an elongatedflexible element with locking elements at its two ends. The meshedmember covers the top and the top rim of the bottom member and, then, isframed and fixed to the bottom member by the rim member and theapplication of a number of bolts through the bolt holes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following descriptions are of exemplary embodiments only, and arenot intended to limit the scope, applicability or configuration of theinvention in any way. Rather, the following description provides aconvenient illustration for implementing exemplary embodiments of theinvention. Various changes to the described embodiments may be made inthe function and arrangement of the elements described without departingfrom the scope of the invention as set forth in the appended claims.

As shown in FIG. 4, a meshed seat cushion 2 according to an embodimentof the present invention contains at least a bottom member 3, a meshedmember 4, a rim member 5, and a number of elastic members 6.

The bottom member 3 has a basin shape with a number of bolt holes 331configured around its top rim 33. Inside the bottom member 3, there area number of supporting elements 31 configured along two opposing sidesof the bottom member 3. On top of each of the supporting elements 31,there are bolt holes 311. Also, at and along the bottom of the bottommember 3, there could be at least a reinforcing element 32 to make thebottom member 3 more rigid and reliable. Please note that the supportingelements 33 also help to reinforcing the rigidity of the bottom member3.

The meshed member 4 is a sheet having a large number of meshes and anappropriate elasticity. The rim member 5 is a hollow frame having ashape and dimension matching those of the rim 33 of the bottom member 3and, therefore, the rim member 5 could cover and wrap the rim 33 of thebottom member 3. Each of the elastic members 6 has at least an elongatedflexible element 62 with locking elements 61 at its two ends. Thelocking element 61 has through holes 611 corresponding to the bolt holes311 on the supporting element 31.

To assemble the meshed seat cushion 2, first, the elastic members 6 arelaid across the top of the bottom member 3 so that its locking elements61 have their through holes 611 matched to the bolt holes 311 of twoopposing supporting element 31 respectively. Then, bolts S1 are screwedinto the bolt holes 311 through the through holes 611 from top to bottomso as to fix the locking elements 61 to the supporting elements 31. Assuch, the elastic members 6 are suspended and stretched across the topof the bottom member 3. Subsequently, the meshed member 4 is used tocover the top and the top rim of the bottom member 3 and the rim member5 is used to frame the meshed member 4 to the bottom member 3. Then, thebolts S2 are screwed into the rim member 5 from bottom to top throughthe meshed member 4 and the bolt holes 331 on the rim 33 of the bottommember 3. The assembled meshed seat cushion 2 is illustrated in FIGS. 5and 6.

As shown in FIG. 7, when a user is sitting on the meshed seat cushion 2,the meshed member 4 would sink under the weight of the user. However,due to the configuration of the elastic members 6 under the meshedmember 4, a large part of the user's weight is actually absorbed by theelastic members 6. As such, the flexible elements 62 not only improvethe comfort of the user, but also provide support to the meshed member 4so that it wouldn't deform after a long period of usage and that itsventilation capability could still be maintained. The operational lifeof the meshed seat cushion 2 is therefore extended significantly.

It will be understood that each of the elements described above, or twoor more together may also find a useful application in other types ofmethods differing from the type described above.

While certain novel features of this invention have been shown anddescribed and are pointed out in the annexed claim, it is not intendedto be limited to the details above, since it will be understood thatvarious omissions, modifications, substitutions and changes in the formsand details of the device illustrated and in its operation can be madeby those skilled in the art without departing in any way from the spiritof the present invention.
